PIC32MZ0512EFF144-I/PH - 32-bit MIPS MCU 200MHz 512KB Flash TQFP-144
The Microchip Technology PIC32MZ0512EFF144-I/PH is a 32-bit MIPS M-Class PIC32MZ microcontroller running up to 200 MHz, integrating 512 KB Flash and 128 KB SRAM in a 144-pin TQFP (16x16 mm) package, designed for industrial, IoT, graphics HMI, motor control, and automotive connectivity applications. This MCU belongs to the PIC32MZ EF family, which combines a high-performance MIPS microAptiv core with rich connectivity peripherals including Ethernet, USB, CAN, and multiple serial interfaces. Per the Microchip product page, the family supports 252 MHz operation and up to 2 MB Flash with 512 KB SRAM, but this specific variant is the 512 KB Flash, 128 KB SRAM, non-crypto industrial-grade member in the 144-pin TQFP.
A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit CPU core, program memory (Flash), data memory (SRAM), and a rich set of on-chip peripherals such as ADCs, timers, communication controllers, and GPIO. Within the embedded device taxonomy, an MCU belongs to the semiconductor > integrated circuit > microprocessor hierarchy and is the system-on-chip of choice for deeply embedded, deterministic applications where a high-level operating system is not required. The PIC32MZ EF family targets the upper end of performance for MCU-class devices, bridging the gap between classic microcontrollers and application-class processors.
Key features of the PIC32MZ0512EFF144-I/PH include 200 MHz maximum CPU clock, 512 KB Flash program memory, 128 KB SRAM, integrated FPU, multiple connectivity peripherals (Ethernet MAC, USB 2.0 OTG, CAN, I2C, SPI, UART), up to 53-channel 12-bit ADC, and an operating temperature range of -40C to +85C (industrial grade). The 144-pin TQFP package provides abundant I/O for graphics, motor control, and parallel display interfacing.
The architecture uses a MIPS32 microAptiv M-Class core with hardware multiply/divide and an FPU, supporting DSP-style operations. The bus matrix provides high-bandwidth access between the CPU, DMA, and peripherals, and the integrated DMA controller offloads data movement from the CPU for efficient throughput in audio, graphics, and communication pipelines.
Typical applications include industrial control and HMI panels, IoT edge gateways, motor control drives (BLDC, PMSM, stepper), graphic displays with integrated TFT controllers, automotive connectivity modules, and high-performance sensor fusion. The 200 MHz flexibility of the device allows high-speed digital signal processing and protocol handling in real time.
When designing with the PIC32MZ0512EFF144-I/PH, ensure proper 3.3V power decoupling near the VDD pins and route analog/digital grounds carefully to avoid ADC noise. The 144-pin TQFP requires a 4-layer PCB with adequate thermal vias under the exposed die pad for high-current applications.
This page synthesizes distributor pricing, drop-in alternatives within the PIC32MZ EF family, and practical design notes not found in the manufacturer datasheet, including the EF vs E variant distinction and the I/PH industrial temperature/package code.
